Method: This prospective study included 104 pregnant women inAactive labor with ruptured membranes at D & uuml;zce University Health Application and Research Center from April 2023 to April 2024. ITU measured the angle of progression (AoP), head-perineum distance (HPD), and midline angle (MLA). These parameters were compared with digital vaginal examinations and delivery outcomes. Results: Of the participants, 93 (89.4%) had spontaneous vaginal deliveries (SVD), 6 (5.7%) had operative vaginal deliveries (OVD), and 5 (4.8%) had cesarean sections (C/S). AoP1 and AoP2 were significantly higher in the SVD group compared to OVD and C/S groups (p<0.001). The Delta AoP was significantly lower in the OVD group (p=0.044). HPD1 and HPD2 were significantly higher in the C/S group (p=0.031 and p=0.041, Arespectively). MLA1 and MLA2 were significantly lower in the SVD group (p=0.002 and p=0.001, Arespectively). Conclusions: ITU is a valuable tool in predicting delivery mode. AoP, HPD, and MLA measurements provide objective and reliable data to assist clinicians in labor management. Further research with larger sample sizes is needed to validate these findings and establish standardized protocols for clinical use.en10.18521/ktd.1632264info:eu-repo/semantics/closedAccessIntrapartum Transperineal UltrasoundPredicting Delivery ModeAngle of ProgressionHead-Perineum DistanceArticle1721891951321034WOS:001531309100001N/A
